CAN Interface Communications
CAN (Controller Area Network) is a two-wire, serial communication bus. It
eliminates polling sequences that verify task completion. Using CAN, the pumps
asynchronously report to the master or host when they have finished the current
task.
Note: All Tecan XLP 6000 systems use CAN controller chips compatible with
Phillips Semiconductor CAN bus specification, version 2.0.
When using the CAN interface, termination resistors (120 ohm) are necessary at
both ends of the bus. The pump does not provide CAN termination resistors.
CAN Messages
CAN messages consist of
frames
. Each frame has an 11-bit Message Identifier
(MID) and a 4-bit length identifier. The bits:
Indicate to which device on the bus the message is directed
Identify the message type
Show the direction of the message (to or from the master device)
